New Delhi: Investigators have found no abnormality in the fuel control switch locking mechanism of the Air India Boeing Dreamliner that crashed just 35 seconds after taking off from Ahmedabad airport on June 12 last year, killing 260 people on board and on the ground, the government said on Wednesday. While the fuel control switch has been cleared of any defect so far, the examination of the complete thrust control module is still underway, with investigators awaiting the outcome of the ongoing inspection. The minister also told the Parliament that the Aircraft Accident Investigation Bureau's (AAIB) final report has not been delayed, maintaining that investigations into major air crashes are an evolving process and that the AI-171 flight crash probe is now in its final stages.
